Can diamond sublime at any pressure up to 1011 Pa? Explain your answer.
Yes, it can sublime to the liquid state
• Yes, it can sublime to graphite.
• No, it cannot sublime because diamond doesn't have a triple point.
• No. It cannot sublime because the gas phase is not adjacent to diamond.
No, it cannot sublime because the gas phase is not adjacent to diamond.
Sublimation is the process in which a substance transitions directly from a solid to a gas without passing through the liquid phase. In order for a substance to sublime, the gas phase must be adjacent to the solid phase. In the case of diamond, it does not have a stable liquid phase at any pressure up to 1011 Pa. Instead, it transitions from solid diamond to gaseous carbon atoms, bypassing the liquid phase entirely. Therefore, diamond cannot sublime at any pressure up to 1011 Pa.
